Development of a rational design methodology for precast concrete slender spandrel beams: Part 2, analysis and design guidelines

Abstract

■ This paper summarizes the results of an analytical research program undertaken to develop a rational design procedure for precast concrete slender spandrel beams.■ The analytical and rational models use test results and research findings of an extensive experimental program presented in a companion paper.■ The overall research effort demonstrated the validity of using open web reinforcement in precast concrete slender spandrel beams and proposed a simplified procedure for design.

Análise e dimensionamento de vigas de seção “L” de concreto pré-moldado utilizando o Método das Bielas

“…Os principais trabalhos relacionados ao comportamento sistemático das vigas de seção "L" começaram a ser desenvolvidos na década de 80 por Raths (1984) e Klein (1986) motivados por acidentes ocorridos em estruturas pré-moldadas. No campo do dimensionamento merecem destaque os trabalhos de Zia e McGee (1978), Collins e Mitchell (1980), Zia e Hsu (2004) e Lucier et al (2011b).…”

Development of a rational design methodology for precast concrete slender spandrel beams: Part 1, experimental results

“…The main objective of this research program was to develop rational design guidelines for precast concrete slender spandrel beams. These design guidelines, presented in a companion paper, 8 are expected to simplify the reinforcement detailing required for slender spandrels, especially in der spandrel beam is subjected to a series of discrete eccentric loadings (Fig. 1).…”

“…The observed end-region failure mode forms the basis of the rational design approach introduced in the companion paper. 8 The typical end-region failure mode is shown in more detail in Fig. 11 and 12.…”
